Description
Technical field
This utility model relates to technical field of generators, a kind of fan blade for automobile current generator with
Rotor fixed form.
Background technology
Traditional automobile-generator fan blade uses spot-welding technology that fan blade is welded on rotor claw and extremely goes up, extremely
Under the conditions of harsh climate, it may appear that solder joint failure situation, to this end, it is proposed that a kind of automobile current generator
Fan blade and rotor fixed form.
Utility model content
The purpose of this utility model is to provide a kind of fan blade for automobile current generator and rotor fixing side
Formula, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of for automobile current generator
Fan blade and rotor fixed form, including axle, described axle be axially socketed with the most successively pawl pole,
Fan blade and back-up ring, axle is machined with knurling, plays circumferentially positioned effect.
Preferably, described pawl pole, fan blade and back-up ring are all installed with axle interference fit.
Preferably, described pawl pole is in close contact with the side of fan blade, and the side of fan blade and back-up ring closely connects
Touch.
Compared with prior art, the beneficial effects of the utility model are: the fan blade of this automobile current generator with turn
Sub-fixed form uses fan blade press-loading process, it is not necessary to fan blade can be fixed on rotor by welding procedure, even
Connect reliable, good environmental adaptability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 axle, 2 back-up rings, 3 fan blades, 4 pawl poles.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Fig. 1, a kind of technical scheme of this utility model offer: a kind of fan blade for automobile current generator are provided
With rotor fixed form, including axle 1, the axial of axle 1 is socketed with pawl pole 4, fan blade 3 the most successively
With back-up ring 2, pawl pole 4, fan blade 3 and back-up ring 2 are all installed with axle 1 interference fit, can use when assembling
Hydraulic press, pawl pole 4 is in close contact with the side of fan blade 3, and the side of fan blade 3 and back-up ring 2 closely connects
Touch, prevent fan blade 3 from moving left and right when high-speed rotation, be possible to prevent fan blade 3 loose or dislocation, and axle 1
On be machined with knurling, play circumferentially positioned effect.The fan blade 3 of this automobile current generator is adopted with rotor fixed form
With fan blade 3 press-loading process, it is not necessary to fan blade 3 can be fixed on rotor by welding procedure, connect reliable,
Good environmental adaptability.
Embodiment the most of the present utility model, for the ordinary skill people of this area
For Yuan, it is possible to understand that can be real to these in the case of without departing from principle of the present utility model and spirit
Executing example to carry out multiple change, revise, replace and modification, scope of the present utility model is by claims
And equivalent limits.
